Summary

Primary hepatic angiosarcoma (PHA) and fat-poor angiomyolipoma (AML) are rare liver cancers. Imaging aids diagnosis, but biopsy remains essential for definitive identification of these vascular tumors.

Area of Science:

  • Hepatology
  • Oncology
  • Vascular Tumors

Background:

  • Primary hepatic angiosarcoma (PHA) and fat-poor angiomyolipoma (AML) are rare vascular liver tumors.
  • Accurate diagnosis is crucial for effective clinical management.
  • Imaging and pathology are key diagnostic modalities.

Observation:

  • A 50-year-old female with VHL Syndrome presented with nonspecific symptoms.
  • Imaging revealed a liver lesion without detectable fat.
  • Initial evaluation considered AML due to VHL Syndrome history.

Findings:

  • A histopathological diagnosis confirmed fat-poor angiomyolipoma (AML) with 5% fat content.
  • PHA and fat-poor AML are uncommon liver malignancies with similar incidences.
  • Contrast-enhanced imaging techniques (CEUS, CECT, CEMRI) are valuable.

Implications:

  • Accurate differentiation of PHA and fat-poor AML is critical.
  • Advanced imaging improves diagnostic confidence.
  • Biopsy is indispensable for definitive diagnosis of these rare liver tumors.
